Sustainable Food Systems

Food demand is expected to rise by 70% to 2050. Urbanisation and increasing incomes per capita are shifting diets to those more demanding of meat and other animal products, which has serious implications for the use of natural resources to produce food. Today around 1 in 8 people are malnourished and 870 million people chronically hungry, indicating our current food systems cannot meet present demand let alone future. Modifying the world’s food production systems to produce more food and perhaps distribute it more evenly, is made harder by a growing recognition of the negative impacts agriculture can have on the environment. Conversion of land to agriculture is the biggest threat to biodiversity. Agriculture places large demands on scarce natural resources, the overuse of which not only threatens the wider global environment and human wellbeing, but the very processes agriculture relies on e.g. pest control, pollination and rainfall.
